摘要

Improved strain gage unit, being of the metallic type constituted by a rectangular plate weakened by perforations, is essentially characterized in that said perforations being four in number and aligned orthogonally, they are located closer to one of the smaller sides than to the other, and the perforations, being circular, are longitudinally joined two to two by gorges, with the particularity that close to the perforations furthest from one of the sides a parallel and transversal groove has been provided from one perforation to another, of medium diameter medium diameter, which in the wall adjacent to the perforations is decreased in the thickness and presents internal weakening by emptying in half a reed, all this so that the inner wall of the perforations has been lowered tangentially to ninety degrees forming a corner slightly rounded between the perforation, the space that separates them transversally and the p contiguous ared of the transversal throat. 2.unit for extensiometric bands perfected.
